I recently had to buy these for the second time after mine got jacked in a pub. I didn't realise how much I loved having them until they were gone. They aren't light, but the build quality is a galaxy apart from the Beats or Marshall range.
On account of being clumsy I pick items on robustness - these survived several train trips to the north in full on rain and sleet and had no complaints, they even kept my ears warm. Hundreds of tube journeys and one truly awful Christmas coach ride. I haven't been on a plane with them yet, I try to avoid those. In all, They earned being puchased again.
Update: Master & Dynamic have a half price WFH sale on, which sucks for me, it came out a few days after I got my replacements. But awesome for you.
